Abstract
A television receiver which receives television signals to display images on a CRT display, and includes a JPEG decode unit ( 21 ) for decoding JPEG (Joint Photographic Experts Group) compressed image data. The JPEG decode unit ( 21 ) detects image size of image data after decode processing stored in JPEG compressed image data from a memory card ( 6 ). In case the image size is larger than image display area of a CRT display ( 3 ) and activity ratio of a memory unit ( 22 ) is larger than a limit value, the JPEG decode unit ( 21 ) sends the image size to a CPU ( 25 ), and concurrently decodes the JPEG compressed image data in the memory unit ( 22 ) to generate the image data, and clips away half of the image data along the vertical direction and the horizontal direction. The image data process unit ( 23 ) enlarges or reduces the image data so that the image data is displayed on substantially the whole image display area without changing the aspect ratio of the image data based on enlargement/reduction ratio which is determined by the CPU ( 25 ) by comparing the image size with the image display area of the CRT display ( 3 ).

Therefore, because storage card 6 can removably be used, therefore can in HDTV 1, use the jpeg compressed image data of gathering by such as digital camera.
Below with reference to Fig. 5, obviously show the configuration of control unit 5.Indicative control unit 5 comprises: JPEG decoding unit 21 is used to the jpeg compressed image data of decoding and importing; Memory cell 22 is used for temporarily storing decoded image data; Image data processing unit 23 is used for amplifying or down scaling image data; Frame memory 24 is used for the data of amplifying or dwindle are formed a line; CPU (CPU) 25.
At this moment, if the detected image size of view data is greater than the image display area of CRT monitor 3, and the activity ratio of the memory cell 22 that the memory capacity of and memory cell 22 big or small from the detected image of view data is calculated is greater than a predetermined limiting value, then JPEG decoding unit 21 excises or removes the part of the decode image data of decoding in memory cell 22 to reduce the image size along vertical direction and horizontal direction, and the view data that will so reduce sends to image data processing unit 23, and the image size that will so reduce after excision is handled sends to CPU 25 simultaneously.
Ratio amplifies or down scaling image data according to the amplification of the view data of being determined by CPU 25/dwindle for image data processing unit 23, so that it is consistent with pixel quantity along the image display area of the CRT monitor 3 of vertical direction along the quantity of the pixel of the view data of vertical direction, perhaps consistent with pixel quantity along the image display area of the CRT monitor 3 of horizontal direction along the pixel quantity of the view data of horizontal direction, and need not change the ratio of width to height from the view data of JPEG decoding unit 21, and the image data storage that will so amplify or dwindle is in frame memory 24, and sends the view data of amplifying or dwindling to CRT monitor 3.
On the other hand, when the enlarged image data, image data processing unit 23 can be inserted into new view data in the described view data.And the center of the image data processing unit 23 feasible view data of amplifying or dwindling is consistent with the center of CRT monitor 3.
Then, explanation will send to the jpeg compressed image data of the different images size of indicative control unit 5.For example, suppose that image size after its decoding processing is that the jpeg compressed image data of 2400 pixels * 1800 pixels (about 4.3 mega pixels), 640 pixels * 480 pixels (about 0.31 mega pixel), 2400 pixels * 1200 pixels (about 2.9 mega pixels), 640 pixels * 360 pixels (about 0.23 mega pixel) are sent to indicative control unit 5.
Image size after its decoding processing is that the jpeg compressed image data of 2400 pixels * 1800 pixels are greater than 1632 pixels * 918 pixels as the image display area of CRT monitor 3.Therefore, can not be presented at from the view data that the jpeg compressed image data produce on the image display area of the CRT monitor 3 that its ring-type is kept perfectly.
In this case, promptly, when to memory cell 22 read the jpeg compressed image data and by JPEG decoding unit 21 to its decoding in, if the activity ratio of memory cell 22 (activityratio) is greater than the limiting value of determining in advance, particularly, the decode image data of 2400 pixels * 1800 pixels is with the hemisection of its vertical direction and the view data on the horizontal direction, to become 1200 pixels * 900 pixels (about 1.1 mega pixels), so that make the image display area of decoded image data less than CRT monitor 3.And, because the image display area of CRT monitor 3 is 1632 pixels * 918 pixels, the decode image data that then so reduces is amplified to 1.02 times becoming 1224 pixels * 918 pixels along vertical direction and horizontal direction in image data processing unit 23, so that consistent with the pixel quantity along the image display area of vertical direction along the pixel quantity of the enlarged image data like this of vertical direction.
On the other hand, if unrestricted to the activity ratio of memory cell 22, then the jpeg compressed image data are not excised processing in JPEG decoding unit 21.Because the image display area of CRT monitor 3 is 1632 pixels * 918 pixels, then decoded image data is narrowed down to 0.51 times becoming in 1224 pixels * 918 pixels along vertical direction and horizontal direction in image data processing unit 23, so that consistent with quantity along the pixel of the image display area of vertical direction along the pixel quantity of the view data of so dwindling of vertical direction.
Image size after its decoding processing is that the jpeg compressed image data of 640 pixels * 480 pixels are less than the zone as 1632 pixels * 918 pixels of the image display area of CRT monitor 3.In this case, because the activity ratio of memory cell 22 is low, the jpeg compressed image data are not excised processing in JPEG decoding unit 21.Because the image display area of CRT monitor 3 is 1632 pixels * 918 pixels, therefore decoded image data is amplified to 1.9125 times along vertical direction and horizontal direction in image data processing unit 23, becoming 1224 pixels * 918 pixels, so that consistent with quantity along the pixel of the image display area of vertical direction along the quantity of the pixel of the enlarged image data like this of vertical direction.
Image size after its decoding processing is that the jpeg compressed image data of 2400 pixels * 1200 pixels are greater than the zone as 1632 pixels * 918 pixels of the image display area of CRT monitor 3.Therefore, can not be displayed on the image display area of CRT monitor 3 from the view data that the jpeg compressed image data produce, and keep its ring-type complete.
In this case, promptly, when to memory cell 22 read the jpeg compressed image data and by JPEG decoding unit 21 to its decoding in, under the situation of the activity ratio of memory cell 22 greater than the limiting value of determining in advance, particularly, the decode image data of 2400 pixels * 1200 pixels is with the hemisection of its vertical direction and the view data on the horizontal direction, to become 1200 pixels * 600 pixels (about 0.72 mega pixel), so that make the image display area of decoded image data less than CRT monitor 3.And, because the image display area of CRT monitor 3 is 1632 pixels * 918 pixels, the decode image data that then so reduces is amplified to 1.36 times becoming 1632 pixels * 792 pixels along vertical direction and horizontal direction in image data processing unit 23, so that consistent with the pixel quantity along the image display area of horizontal direction along the pixel quantity of the enlarged image data like this of horizontal direction.
On the other hand, if unrestricted to the activity ratio of memory cell 22, then the jpeg compressed image data are not excised processing in JPEG decoding unit 21.Because the image display area of CRT monitor 3 is 1632 pixels * 918 pixels, then decoded image data is narrowed down to 0.68 times becoming 1632 pixels * 792 pixels along vertical direction and horizontal direction in image data processing unit 23, so that consistent with the pixel quantity along the image display area of horizontal direction along the pixel quantity of the view data of so dwindling of horizontal direction.
Image size after its decoding processing is that the jpeg compressed image data of 640 pixels * 360 pixels are less than the zone as 1632 pixels * 918 pixels of the image display area of CRT monitor 3.In this case, because the activity ratio of memory cell 22 is low, the jpeg compressed image data are not excised processing in JPEG decoding unit 21.Because the image display area of CRT monitor 3 is 1632 pixels * 918 pixels, therefore decoded image data is amplified to 2.55 times along vertical direction and horizontal direction in image data processing unit 23, becoming 1632 pixels * 918 pixels, so that consistent with pixel quantity along the image display area of horizontal direction along the pixel quantity of the enlarged image data like this of horizontal direction.
Then, reference flow chart shown in Figure 6 illustrates the processing of HDTV 1, and its decoding is recorded in the jpeg compressed image data in the storage card 6 that is installed on the Storage Card Drivers device 4, and shows decoded image data like this on CRT monitor 3.
At step S1, the jpeg compressed image data of JPEG decoding unit 21 receiving records in storage card 6, and the image size of detection of stored view data in the frame headers of jpeg compressed image data, after decoding processing.
At step S2, JPEG decoding unit 21 judges whether the image display area of the image size of the view data that detects like this greater than CRT monitor 3.If the size of the view data that is detected greater than the image display area of CRT monitor 3, is then handled and is proceeded to step S3, otherwise, handle proceeding to step S4.
At step S3, JPEG decoding unit 21 judges whether that the activity ratio of the memory cell 22 that the memory capacity of and memory cell 22 big or small from the image of the view data that is detected is calculated is greater than the limiting value of determining in advance.If the activity ratio of memory cell 22 greater than limiting value, is then handled and is proceeded to step S5, otherwise, handle proceeding to step S4.
At step S4, JPEG decoding unit 21 sends the image size of the view data that is detected to CPU 25, jpeg compressed image data in memory cell 22 decode simultaneously so that produce view data, and the view data that will so produce sends to graphics processing unit 23.
At step S5, JPEG decoding unit 21 sends the image size of the view data that is detected to CPU 25, jpeg compressed image data in memory cell 22 decode simultaneously so that produce view data, also along half of vertical direction and horizontal direction excision view data so that the image size is reduced to its 1/4, so that make decoded image data, and send the view data of so dwindling to image data processing unit 23 less than the image display area of CRT monitor 3.
At step S6, CPU 25 compares the image size of the view data that received with the image display area of CRT monitor 3, and the amplification of definite view data/dwindle ratio is with the amplification that will so determine/dwindle ratio to send to image data processing unit 23.
At step S7, ratio amplifies or down scaling image data according to the amplification of being determined by CPU 25/dwindle for image data processing unit 23, so that it is consistent with pixel quantity along the image display area of the CRT monitor 3 of vertical direction along the pixel quantity of the view data of vertical direction, perhaps consistent with pixel quantity along the image display area of the CRT monitor 3 of horizontal direction along the pixel quantity of the view data of horizontal direction, and do not change the ratio of width to height from the view data of JPEG decoding unit 21.
At step S8, image data processing unit 23 is stored the view data of so amplifying or dwindling in frame memory 24.
At step S9, image data processing unit 23 makes that the center of the view data that writes is consistent with the center of CRT monitor 3 in frame memory 24, and at the image display area display image data of CRT monitor 3.
The same, receive by digital camera according to HDTV 1 of the present invention, record such as personal computer, and its image after decoding processing varies in size in the various jpeg compressed image data of storage card 6, amplify or dwindle this view data, so that it is consistent with pixel quantity along the image display area of the CRT monitor 3 of vertical direction along the pixel quantity of the view data of vertical direction, perhaps consistent with pixel quantity along the image display area of the CRT monitor 3 of horizontal direction along the pixel quantity of the view data of horizontal direction, and need not change the ratio of width to height of decoded view data, perhaps keep ring-type complete.
Therefore, HDTV 1 is the jpeg compressed image data of displayed record in storage card 6 on the entire image viewing area of CRT monitor 3 roughly, and this makes the user to watch TV programme and does not feel well suitable.
